Foundation repair prices in Houston

Most foundation repair jobs in Houston cost between $3,300 and $6,800, according to a 2026 Houston Press guide. Small fixes cost far less: sealing a crack runs about $250 to $800. Severe settling that needs a full lift can reach $20,000 or more. The biggest driver is how many foundation piers the house needs, followed by whether any go indoors and how easy the site is to work on. Most Houston homes sit on a concrete slab, so slab foundation repair is the most common job here. Below you'll find prices by method, what moves a quote up or down, what to do if the number is more than you can pay, and how to compare quotes.

What is the average cost of foundation repair in Houston?

The average Houston job falls between $3,300 and $6,800, based on the 2026 Houston Press guide. Nationally, This Old House reports a range of $2,224 to $8,134 and an average of $5,179. Houston prices sit inside that national band because most local work is piering under a slab, and pressed concrete piers here cost about $300 to $600 each.

The work is common here because of the ground. Lake Charles clay, 45 to 60% clay by USDA figures, cracks open in dry months and swells when water returns, so slabs rise and drop unevenly. Subsidence adds to it: the fastest measured sinking, over 3 cm a year, is around Katy and Fulshear.

How much does it cost to fix a foundation, by repair method?

The method sets the price more than anything else. Filling cracks costs a few hundred dollars. Mudjacking a sunken slab section costs around $550 to $1,300. Piering, the usual fix for a settling Houston slab, is priced per pier, so a job with ten piers costs roughly ten times a single pier. Lifting and leveling a badly settled house is the top of the scale.

The national per-pier figure covers a wider mix of pier types than the Houston one. For a closer look at single jobs, see foundation crack repair cost and foundation leveling cost.

What makes a foundation repair quote higher or lower?

Four things move the price most: the number of piers, the pier type, whether work happens inside the house, and access. Steel piers cost more than pressed concrete. Interior piers mean cutting through the slab under your floors, which the Houston Press guide says adds about 15%. Decks, tight side yards and planted beds add 6 to 8% to pier costs.

Then come the costs around the repair itself:

• Inspection. About $300 to $1,000 in Houston, with an average near $600. The foundation inspection cost page breaks this down.
• Engineer and soil reports. About $500 to $1,000 for a structural engineer report and $500 to $3,000 for a soil report, nationally.
• Permit. $75 to $150 is the national guide. Inside the City of Houston, foundation repair runs under a building permit, and the city's weekly reports list them. Bellaire charges a flat $130 floodplain development permit for residential foundation work. Online cost calculators use these same inputs but can't count your piers. The foundation repair cost per square foot page explains why size alone is a poor guide.

How much do smaller jobs cost, like leaks, garages and wood rot?

Smaller foundation problems usually cost hundreds to a few thousand dollars rather than the full pier job. A cracked garage slab is often sealed for $250 to $800 or mudjacked for $550 to $1,300. Leaks and rotted wood on pier-and-beam houses are priced after an inspection, because the cause decides the fix. Ignoring them is what makes them expensive.

• Leaky foundations. Houston has almost no basements, so a leak here usually means water coming through a slab or a plumbing leak under it. Find the source before paying for sealing.
• Garage slabs. These often settle separately from the house. Cracks without height change are usually just sealed.
• Wood rot. Older pier-and-beam homes can have rotted sills, beams or wood piers, priced by how many need replacing. See pier and beam foundation repair cost.

This Old House notes that a hairline crack sealed for $250 to $800 can turn into a $10,000 to $15,000 structural repair if it's left to grow.

What can you do if you can't afford foundation repairs?

Start by getting the problem diagnosed and the repair priced in writing, then decide what must happen now and what can wait. Ask whether the work can be split into stages, starting with the section that's moving most. Check what your homeowners insurance says, look into city repair programs, and ask contractors whether they offer payment plans.

1. Fix the water first. Gutters and downspouts that drain away from the slab cost little and can slow movement while you save.
2. Stage the repair. Stabilize the worst corner now and leave cosmetic wall and floor repair for later.
3. Check your policy. Read insurance and foundation repair before you file.
4. City programs. The City of Houston's Housing and Community Development department runs home repair programs for owner-occupied homes with income at or below 80% of area median income. Several were closed or paused when we checked, so ask about current funding.
5. Financing. Compare the total cost of any payment plan, not just the monthly figure.

How do you compare foundation repair quotes and warranties?

Compare quotes line by line: the number of piers, the pier type, where each pier goes, interior versus exterior work, permits, and what the warranty covers. Two quotes with the same total can describe very different repairs. The cheaper one may use fewer piers or shallower ones, which can leave part of the house free to keep moving.

Ask each contractor for a pier log showing each pier's depth, who pulls the permit, and what the written warranty covers, for how long, and whether it transfers if you sell.

When you send a request through this site, we'll arrange a visit from a local foundation contractor, and the price comes in writing after they've seen the house. The figures on this page are a guide only. For the wider picture of how repair works here, see foundation repair across Houston.
